NASA is watching closely a 2,000 foot asteroid that will come within 334,000 miles of Earth at 3:33 a.m. Jan. 29.

So if you are a numbers person you might lay down some money on 3s in Las Vegas.While that distance is “close” in space terms, experts weren’t predicting an Armageddon moment.

Asteroid 2007 TU24 was discovered by the NASA-sponsored Catalina Sky Survey on Oct. 11, 2007. Scientists at NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif., have determined that there is no possibility of an impact with Earth in the foreseeable future, NASA said in a release.

"This will be the closest approach by a known asteroid of this size or larger until 2027," said Don Yeomans, manager of the Near Earth Object Program Office at JPL. "As its closest approach is about one-and-a-half times the distance of Earth to the moon, there is no reason for concern. On the contrary, Mother Nature is providing us an excellent opportunity to perform scientific observations."

NASA noted that on Jan.29 the asteroid will be observable at night from dark locations that have clear skies.A telescope with apertures of at least 7.6 centimeters (3 inches) should be able to see the asteroid.

NASA detects and tracks asteroids and comets passing close to Earth. The Near Earth Object Observation Program, commonly called "Spaceguard," discovers, characterizes and computes trajectories for these objects to determine if any could be potentially hazardous to our planet.
